Question

Determine the are length on a circle of radius 7 and an included angle of 4.5 radians.

Answer 1

The arc length of a circle is 31.5.

Explanation:

The arc length can be found as follows:

`arc = r\theta`

Where:

arc: is the length of the arc of the circle

r: is the radius = 7

θ: is the angle = 4.5 rad

`arc = r\theta = 7*4.5 = 31.5`

Therefore, the arc length of a circle is 31.5.
